On July 15, Aehr Test Systems rose 9.67% in after-hours trading, trading at $83.608/share, with turnover of $17.91 million. The movement was catalyzed by the company's fiscal quarter earnings release alongside sustained momentum from AI chip testing orders.

The company secured a follow-up production order for its silicon photonics wafer-level burn-in system in June, building on a previously announced $41 million AI chip testing contract. Management disclosed that a top-tier AI chip customer had successfully completed a benchmark test spanning over six months, significantly reinforcing expectations for subsequent large-scale orders. Aehr Test Systems is a leading provider of semiconductor wafer-level test, burn-in, and stabilization solutions, with products widely deployed across AI data centers, electric vehicles, and optical communications.
